Sean Callanan b226916528 Implemented an extension to the namespace map that
permits a namespace map to be created and populated
when the namespace is imported, not just when it is
requested via FindExternalVisibleDecls().

Sean Callanan 80c48c10d0 Made the IR interpreter more robust in the presence
of arbitrary pointers, allowing direct dereferences
of literal addresses.  Also disabled special-cased
generation of certain expression results (especially
casts), substituting the IR interpreter.

Greg Clayton 97fbc34276 Fixed some issues where we might not have one of the new apple accelerator
tables (like the .apple_namespaces) and it would cause us to index DWARF that
didn't need to be indexed.

Updated the MappedHash.h (generic Apple accelerator table) and the DWARF
specific one (HashedNameToDIE.h) to be up to date with the latest and
greatest hash table format.

Greg Clayton 64bc6ca595 Modified the ASTDumper to return a "const char *" instead of a copy of the
std::string and modified all places that used the std::string it returned
to use the "const char *".

Also modified the expression parser to not crash when a function type fails
to copy into the expression AST context.

Greg Clayton 81c22f6104 Moved lldb::user_id_t values to be 64 bit. This was going to be needed for
process IDs, and thread IDs, but was mainly needed for for the UserID's for
Types so that DWARF with debug map can work flawlessly. With DWARF in .o files
the type ID was the DIE offset in the DWARF for the .o file which is not
unique across all .o files, so now the SymbolFileDWARFDebugMap class will
make the .o file index part (the high 32 bits) of the unique type identifier
so it can uniquely identify the types.

Greg Clayton 85ae2e1349 Changed lldb_private::Type over to use the intrusive ref counted pointers
so we don't have to lookup types in a type list by ID.

Changed the DWARF parser to remove the "can externally complete myself" bits
from the type when we are in the process of completing the type itself to
avoid an onslaught of external visible decl requests from the 
clang::ExternalASTSource.

Sean Callanan 35c7f98734 Improved logging, replacing the old ASTDumper (which
we never used) with a much simpler class that wraps
the relevant dump functions in Clang.  This class also
knows to disable external lookups on DeclContexts
being dumped so it should be safe to print incomplete
Decls.

Jason Molenda e858e33200 Add code to RegisterContextLLDB::InitializeNonZerothFrame to detect a multiple stack frames
with the same CFA (or an alternating sequence between two CFA values) to catch a handful of
unwind cases where lldb will inf loop trying to unwind a stack.

Enrico Granata a9dbf4325e this patch introduces a new command script import command which takes as input a filename for a Python script and imports the module contained in that file. the containing directory is added to the Python path such that dependencies are honored. also, the module may contain an __lldb_init_module(debugger,dict) function, which gets called after importing, and which can somehow initialize the module's interaction with lldb

Johnny Chen 16dcf718d3 Add a commnad to set a condition for a watchpoint. Example:
watchpoint modify -c 'global==5'

modifies the last created watchpoint so that the condition expression
is evaluated at the stop point to decide whether we should proceed with
the stopping.

Also add SBWatchpont::SetCondition(const char *condition) to set condition
programmatically.

Test cases to come later.

Sean Callanan 7dd9812675 Improved expression logging. Now all calls to
FindExternalVisibleDecls and FindExternalLexicalDecls
are marked and given unique IDs, so that all logging
done as part of their execution can be traced back to
the proper call.

Also there was some logging that really wasn't helpful
in most cases so I disabled it unless verbose logging
(log enable -v lldb expr) is enabled.

Johnny Chen ed456eb0a9 Add SBWatchpoint::GetError() API, which is not currently populated as yet.
llvm-svn: 141979
2011-10-14 19:15:48 +00:00
Greg Clayton 5a31471e72 Added the ability to run expressions in any command. Expressions can be
inserted in commands by using backticks:

(lldb) memory read `$rsp-16` `$rsp+16`
(lldb) memory read  -c `(int)strlen(argv[0])` `argv[0]`

The result of the expression will be inserted into the command as a sort of
preprocess stage where this gets done first. We might need to tweak where this
preprocess stage goes, but it is very functional already.

Added ansi color support to the Debugger::FormatPrompt() so you can use things
like "${ansi.fg.blue}" and "${ansi.bold}" many more. This helps in adding 
colors to your prompts without needing to know the ANSI color code strings.

Johnny Chen f5be9e3759 Add a test case to exercise the newly added SB API:
lldb::SBWatchpoint
SBTarget::WatchAddress (lldb::addr_t addr, size_t size, bool read, bool write)

Sean Callanan 187de46132 Improved logging for FindExternalLexicalDecls to
make it easier to track down which members belong
to which structs (and which call to 
FindExternalLexicalDecls is doing the reporting).

2011-10-14 01:15:27 +00:00
Johnny Chen 01a678603a SBValue::Watch() and SBValue::WatchPointee() are now the official API for creating
a watchpoint for either the variable encapsulated by SBValue (Watch) or the pointee
encapsulated by SBValue (WatchPointee).

Removed SBFrame::WatchValue() and SBFrame::WatchLocation() API as a result of that.

Modified the watchpoint related test suite to reflect the change.

Plus replacing WatchpointLocation with Watchpoint throughout the code base.

There are still cleanups to be dome.  This patch passes the whole test suite.
Check it in so that we aggressively catch regressions.

Greg Clayton cb5860a70b Modified the DWARF parser to take care of a 1 clang::DeclContext to many
DIEs. Prior to this fix, there was a 1 to 1 mapping.

llvm-svn: 141917
2011-10-13 23:49:28 +00:00
Greg Clayton 20568dd981 Fixed a case where we might end up trying to parse a type in the DWARF parser for a method whose class isn't currently in the process of completing itself. Currently, methods of a class, must be parsed when the class type that contains the method is asked to complete itself through the clang::ExternalASTSource virtual functions. Now we "do the right thing" by checking if the class is being defined, and if so we parse it, else we tell the class to complete itself so everything happens correctly.

Sean Callanan c6bba3e46d Cleaned up a few functions that never get used.
Specifically, the expression parser used to use
functions attached to SymbolContext to do lookups,
but nowadays it searches a ModuleList or Module
directly instead.  These functions had no
remaining clients so I removed them to prevent
bit rot.

I also removed a stray callback function from
ClangExpressionDeclMap.

Sean Callanan ebe6067a8c Enabled the namespace-specific search functionality,
which had previously been commented out while I tested
it.  It's not fully working yet, but it doesn't break
our testsuite and it's an important piece of
functionality.

Also added some logging to SymbolFileDWARF to help
diagnose entities that are found in a symbol file,
but do not reside in the expected namespace.

llvm-svn: 141894
2011-10-13 21:50:33 +00:00
Sean Callanan c41e68b127 Moved the list of found namespaces into the search
context object.  Having it populated and registered
within a single FindExternalVisibleDecls call worked
fine when there was only one call (i.e., when we were
just looking in the global namespace).  

However, now FindExternalVisibleDecls is called for
nested namespaces as well, which means that it is
called not once but many times (once per module in
which the parent namespace appears).  This means that
the namespace mapping is built up across many calls
to the inferior FindExternalVisibleDecls, so I moved
it into a data structure (the search context) that is
shared by all calls.

I also added some logging to make it easier to see
what is happening during a namespace search, and 
cleaned up some existing logging.

Sean Callanan 213fdb8bf6 Completed the glue that passes a ClangNamespaceDecl *
down through Module and SymbolVendor into SymbolFile.
Added checks to SymbolFileDWARF that restrict symbol

Greg Clayton 4f76b23764 Always use the full variable name when dumping globals since they might
be in namespaces.

2011-10-13 01:14:39 +00:00
Greg Clayton aa044960b5 Add a version of ResolveFunction that takes a "const DWARFDebugInfoEntry *"
and a "DWARFCompileUnit *" to avoid doing a DIE lookup twice and to prepare
for using namespaces in the lookups.

llvm-svn: 141843
2011-10-13 00:59:38 +00:00
Sean Callanan 8e5b8b9631 Now that we know the values are going to stick around,
we don't need to look them up again when materializing.

Switched over the materialization mechanism (for JIT
expressions) and the lookup mechanism (for interpreted
expressions) to use the VariableSP/Symbol that were
found during parsing.

llvm-svn: 141839
2011-10-13 00:09:20 +00:00
Greg Clayton bfe3dd4d8b Added a function to test if a ClangNamespaceDecl matches the current symbol
file. This will help us to minimize lookups that can't possibly match anything
in the current symbol file.

llvm-svn: 141838
2011-10-13 00:00:53 +00:00
Greg Clayton 2506a7a959 Added the ability to see if a DIE is contained in a namespace.
llvm-svn: 141832
2011-10-12 23:34:26 +00:00
Sean Callanan e3aef1d063 Extended the lifetime of Clang parser objects to the
lifetime of ClangExpressionDeclMap.  This allows
ClangExpressionVariables found during parsing to be
queried for their containing namespaces during
expression execution.

Other clients (like ClangFunction) explicitly delete
this state, so they should not result in any memory
leaks.

2011-10-12 22:20:02 +00:00
Sean Callanan ca4e0fd7e6 Refactoring in preparation for having multiple
calls to the FindExternalVisibleDecls function.

FindExternalVisibleDecls was recording whether
it had found generic function symbols in variables
that were local to the function.  Now, however,
multiple calls occur in response to one request
from Clang, since we may be searching across
namespaces.  To support that, I moved the local
variables into a bitfield in NameSearchContext.

llvm-svn: 141808
2011-10-12 20:29:25 +00:00
Sean Callanan 1a2c5386cd Made the expression parser's type search call the
proper namespace-aware APIs.

2011-10-12 18:44:30 +00:00
Sean Callanan 4c3977c278 Added support to ClagnExpressionDeclMap for finding
data symbols in namespaces.

llvm-svn: 141792
2011-10-12 18:00:53 +00:00
Sean Callanan 25ea08ef8c Changed FindExternalVisibleDecls() to use the module
level FindFunctions() where appropriate and not use
SymbolContext::FindFunctionsByName().
